Abstract (en)
[origin: EP2664467A1] A tire comprising a tire cavity, a first and a second sidewall (32) extending to a tire tread region is disclosed. An elongate sidewall groove extends into the first tire sidewall from an axially outward first sidewall surface, the sidewall groove having an axially outer groove entry region of a narrower width dimension, and a groove chamber extending axially inward from the groove entry region and having a wider width dimension at an axially inward groove portion than the groove entry region. An elongate air tube (84) is positioned within the elongate sidewall groove in at least partial contacting engagement with the groove primary chamber sidewalls, the air tube comprising a unitary air tube body. An internal air passageway (86) is substantially centrally positioned within the air tube body. The air tube body has an axially outward air tube body portion of narrower transverse width dimension substantially complementary to the groove entry region width dimension, and an axially inward air tube wing portion of wider width dimension substantially complementary to the groove chamber width dimension at the axially inward portion.
